Terrestial axial longitudes run parallel with orbital orientation at
dawn and dusk on the Equinox but this astronomical alignment  is lost
to those who maintain a variation in axial tilt to the Sun as something
observed and actual.It cannot be because this image dictates otherwise-

Do you get paid when someone goes to that link? :-) I can't imagine any other reason to post it over and over again. Taken by itself, it doesn't even prove that the Earth rotates on its axis :-)
Actually, it does show that the Earth's axis is tilted by a constant amount, and sometimes points in the direction of the Sun as the Earth goes through a revolution. You could not take that picture from North of the Arctic Circle in summer, because you would be in perpetual daylight. Look at John Walker's excellent Home Planet program <http://www.fourmilab.ch>, for instance. And look at this suitably elementary page <http://intranet.rocklizard.org/astronomyclass/planetil.htm>. Perhaps you will email the author to correct him (her ?) Be sure to post the reply :-)

Perhaps you could explain the images in this page <http://www.analemma.de/english/analem.html> which provide an insight into the Equation of Time you are so confused about.

George, I think whatever is posting has failed the Turing test. It just posts the same irrelevant links over and over again. Like an ELIZA program that has gone outside its parameters :-)
